As Katy Perry enjoyed a trip to Raging Waters in San Dimas she showed off a little bit too much of her enviable bikini body as she took to a ride in a two-piece.
The singer who is known for her love of amusement parks found herself overexposed when her bottoms slipped down as she went down a water slide.

She showed off a trim figure while looking a little sunburned on her stomach and chest.
